What: The mind is like looking at the ocean. There is a lot to see on the surface, but there is a lot more that's hidden. Mentally, when you analogize, you are going beneath the surface to get something. What are you getting? For any given person, it not clear. But if you want an analogy about an analogy, think of a Pelican diving for a fish. They skim the water's surface looking for something to eat. When they sense that somethings good right below the surface they momentarily plunge below the surface and grab the goodies. Learning with an analogy, a good analogy has a similar feel.
